For a long time, lattice-based cryptosystems have been seen only
as an alternative for current public-key cryptosystems based on factoring and discrete logs
in the event that one day large quantum computers become a reality.
However, this view has changed dramatically in recent years due to several significant results.
As the recent construction of a fully-homomorphic scheme by Gentry has shown,
lattice-based cryptography not only provides an alternative for current public-key cryptosystems,
but it also allows us to build primitives which we did not know how to build based on existing techniques.

Despite the recent advances in the area of lattice-based cryptography and the large interest that it has created in the cryptography community,
these results have only been covered by existing workshops and conferences in a very scattered way.
Hence, the main goal of this workshop is to fill this gap and provide a forum in which researchers
can get together to learn and discuss about recent advances in lattice-based cryptography.
Bibliographies on lattice-based cryptography can be found here and there.
A book surveying the applications of lattices to computer science (including cryptology)
recently appeared (Springer, Series: Information Security and Cryptography, 2009).
